HTC One M8 won't boot past the initial welcome splash screen

Hi all. I have an untampered (stock) with phone that was working well until this week. Nothing happened in particular that I can think of to make it stop working properly, except perhaps the battery fully drained itself.

I have charged the phone for some hours now... although I don't see the charging light, every now and again, a picture of a battery appears on the screen and displays 1%, 6%, etc.

Hitting the power button only brings up the HTC welcome splash screen, and a few seconds later, it goes blank. I can hold the power button + vol down to enter Hboot, but then when I use the power button to select either recovery or factory reset, it simply displays the same HTC welcome splash screen and then goes blank again.

Perhaps the charger is faulty? Shouldn't the phone boot with 6% battery (although I suspect it has charged up further than that, 6% is the last number I saw)?

According to what you say . The phone gone into a deep discharge and battery logic is failing .
Have you tried to reset the charging logic of the device, first you must charge your M8 for a minimum of 10 minutes using a wall charger. Now With the power off from the switch ,press and hold the volume up and down button ( both volume button ) with the power button for approximately 2 minutes. After 2 minutes, release all of the buttons. After the release the charging logic should be reset. Then charge your phone to 100% using your wall charger. If this doesn't work then its probably a failing battery or charge port.

I suspect you are right; perhaps there is something different between from the 110v in USA vs 220v in Norway, but the charge seems much slower in Norway. Perhaps the cable is faulty, or the charging block.

Try using a different wall charger.
Or perhaps a powerful charger to get it a kick start for a short time . And than the normal charger.
But before all this try to reset battery logic . That has worked

Input voltage (mains voltage to the charger) is irrelevant. The output voltage is indicated on the charger (probably 5v). If the phone took 110v or 220v it would probably blow up! The charger brick is essentially a small electrical transformer, which only outputs what the phone will take. You will see on the charger, it will take a range of input voltages (probably 110-240v).

I'm confused why you say it charges much slower in Norway? Did you charge it somewhere else previously?

If you have any reason to think the charger or cable is faulty, I would definitely try another charger and cable.
